ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a high-voltage connector suited for use with electronic apparatuses driven with higher voltages, and more particularly to a connector used in the recent smaller-sized and thinned inverter boards (viz., circuit boards) serving as power supply circuits for the so-called back-light devices that operate as the light beam source for liquid crystal displays.
2. Prior Art
The current notebook type personal computers, for example, have been required to comprise as large liquid crystal displays as possible within a de-limited dimension which the computer body frames afford. Such enlarge displays have necessitated higher voltages amounting to 1000-1400 volts or so to activate the back-light illuminators. Since the printed inverter boards, viz., the power sources, for feeding electric energy to the back-lights have usually been set in those body frames, such larger displays have reduced the surface mount areas allotted to the printed inverter boards, causing same to be made smaller in size.
Connectors each electrically connecting the smaller-sized printed inverter board to the back-light device have thus to be smaller and nevertheless resistant to high voltages. The present applicant has therefore filed a patent application for an invention as disclosed in the Japanese Laying-Open Gazette No. 10-172649. In this preceding invention, linear and spatial distances between the contacts in the connector were increased so that it could withstand high voltages.
The term ‘linear distance’ used herein does define a distance measured along surfaces intervening between such contacts as disposed in combination with each other.
SUMMARY OF THE INVENTION
However, the current market more strongly demands the notebook type personal computers rendered much lighter in weight and much thinner in shape. An object of the present invention that was made to meet these requirements is therefore to provide a high-voltage connector that will not only ensure linear and spatial distances increased between the contacts but also will be rendered smaller in size and thinner in height, by improving the connector proposed in the Gazette No. 10-172649.
In order to achieve this object, a high-voltage connector that is provided herein consists of a base connector mating a socket connector, the base connector comprising: a first insulated housing with a front opening, an input pin contact and an output pin contact, both the pin contacts being held in the first housing, and a partition integral with and dividing the first housing into discrete compartments. The pin contacts are arranged in parallel with each other in the respective compartments, each pin contact consisting of a front portion protruding towards a mouth of the front opening and a rear portion protruding rearwards through a back wall of the first housing. The housing has a middle rear extension jutting backwards from the back wall of the first housing, wherein the rear portion of the input pin contact is bent down to assume an L-shape to thereby form a solderable end, and the rear portion of the output pin contact is bent sideways and outwards and further bent down to assume another L-shape to thereby form a solderable end. The rear portions are isolated from each other by the middle extension so as to ensure between said portions such linear and spatial distances as enhancing high-voltage resisting property of the base connector.
The socket connector comprises: a second insulated housing, and a pair of socket contacts held therein and securable on respective wire ends, the second insulated housing being insertable into the front opening of the first insulated housing through the mouth thereof so as to cause the socket contacts to fit on the front portions of the respective pin contacts. A recess formed in the second housing is adapted to fit on the partition of the base connector. A pair of cylindrical chambers are formed in the second housing and separated with the recess so as to render the second housing bifurcated, so that the chambers accommodate the respective socket contacts isolated from each other and each lying on one side thereof. One of the chambers that holds therein one of the socket contacts for the input pin contact is made longer than the other chamber holding the other socket contact for the output pin contact, whereby linear and spatial distances between the socket contacts are increase enough to enhance high-voltage resisting property of the socket connector.
Preferably, each chamber for the socket contact may have a side wall where a lance is disposed to force each socket contact to lie on its one side.
